Stapes

Stirrup-shaped medial ossicle. Two crura and a footplate. Footplate occupies oval window.

Zoom in, then drag to inspect. Keyboard: + / − to zoom, arrows to pan, 0 to reset. Tap the numbered markers to explore parts.

STRUCTURE & FUNCTION

Understand what you see.

Transmits vibration into inner-ear fluid.

Zoom into the original labels. Practise pointing out each structure, then explain it aloud. Diagrams are teaching references; specimen appearance and slide staining vary.

01 / IDENTIFICATION

How to recognise it.

  1. Stirrup-shaped medial ossicle
  2. Two crura and a footplate
  3. Footplate occupies oval window
02 / KEY STRUCTURES

Point them out.

Tap a number to open its reference, zoom in and locate the structure. Numbers stay the same across views. This key follows landmarks visible in the reference images.

Related features & study points (3)

Additional relations, attachments or microscopic details to revise alongside this plate. These are separate from its numbered image landmarks.

  • Head
  • Anterior and posterior crura
  • Footplate
03 / VIVA PRACTICE

Think first. Then reveal.

Say your answer aloud before opening the suggested response.

Examiner-style prompts: identify the structure, explain its relations, then answer the applied follow-up. These are revision questions, not authenticated past papers.

01Identify stapes and give its main role.
SUGGESTED ANSWER

Stirrup-shaped medial ossicle. Two crura and a footplate. Footplate occupies oval window. Transmits vibration into inner-ear fluid.

02Which nerve supplies stapedius?
SUGGESTED ANSWER

A branch of facial nerve VII. Injury proximal to this branch may cause hyperacusis.

03What holds the footplate at the oval window?
SUGGESTED ANSWER

The annular ligament allows movement while sealing the margin.

04Point out three important relations and explain their significance.
SUGGESTED ANSWER

Head; Anterior and posterior crura; Footplate. Transmits vibration into inner-ear fluid. Use the reference plate to locate the region; the relationship map organises the associations and is not drawn to scale.
